TOY SUBMARINE.

Application filed January 17, 1924. Serial No. 686,714.

The invention relates to toy submarines and its object is to provide a simple device with novel means for propelling it through the water and which will be capable oi submergence to selected distances.

I accomplish the invention by the novel construction and arrangement of parts hereinafter described and illustrated in the drawings in which Figure 1 is a plan view of the device and Fig. 2 a side elevational view of the same partly in section.

In the drawings 1 represents a closed hollow body or shell of selected form having apertures 2 formed at suitable points in its wall for the admission and discharge of water to and from its interior. A weight 3 is secured to the lower or bottom side of the body and a mast or periscope 4c may project upwardly from the top side.

A11 inflatable air bag 5 is within the body and a rubber tube or hose 6 of desirable length is inserted through a wall of the body and is connected to the bag. A compressor bulb 7 is attached to the outer end of. the tube by which the bag may be inflated to expel water from the body to cause the device to rise in the body of water. A float 8 may be secured to the tube at a selected point by which the portion of the tube below the float may be supported so as not to foul the body. The compressor bulb has a valve 9 therein which will admit atmospheric air but will not permit the air under pressure in the bag to escape through the bulb.

At a selected point on the lower side of the body and adjacent the rear end of the same I attach a tube 10 which projects rearwardly from the body and has communication with the interior thereof. A fine rubber tube 11 is connected to the bag 5 and extends into this tube 10, and is open at its outer end to the body of water in which the toy may be placed. This tube serves as an exhaust for the bag. The air under pressure in the bag discharges through the tube 11 in a fine steam and its impact with the water causes the body to move forwardly.

The tube 6 is much larger in diamenter than the tube 11 hence the air bag is easily inflated by compressing the bulb, the escape of the air from the bag being slow yet with sufficient force to propel the device.

To cause the body to submerge, the operation of the bulb is stopped and the discharging air deflates the bag to permit the water to enter through the apertures which causes the body to submerge. By operating the bulb suficiently the depth to which the body shall sink is readily controlled, it being apparent that the depth of submergence is Eegulated by the degree of inflation of the The tube 6 may be of any desired length so that the range of movement of the toy may be of such extent as the user may desire.

l/Vhat I claim is:

1. In a toy, the combination of a hollow body having means therein for normally admitting water from the exterior to cause, the body to sink in water, an inflatable member within the body adapted to expel the water therefrom for controlling the depth of the body in the water, means exteriorly of the body and connected to the inflatable member for inflating the same, a hollow member connected to the inflatable member and projecting through the body and adapted to exhaust the air in a jet from the inflatable member into the surrounding water for propelling the body.

2. In a toy, the combination of a hollow body having ports in its wall for admitting water for causing the body to sink in surrounding water, an inflatable bag within the body for expelling the water therein to cause the body to rise, a tube connected at one end to the bag and projecting from the body, pumping means connected to the other end of the tube for inflating the bag, and a tube connected to the bag and projecting through the body and connnunicating with the surrounding water for dis charging the air under pressure in the bag in a jet into the said water for propelling the body, the said discharge tube being less in diameter than the inflating tube.

3. In a toy, the combination of a hollow body having ports in its wall for admit ting water for causing the body to sink in surrounding water, an inflatable bag within the body for expelling the water therein to cause the body to rise, a tube connected at one end to the bag and projecting from the body, pumping means connected to the other end of the tube for inflating the bag, a float mounted on the tube to prevent the tube from fouling the body, and a tube connected to the bag and projecting through the body and communicating with the surrounding Water for discharging the air under pressure in the bag in a jet into the said water for propelling the body, the said discharging tube being less in diameter than the inflating tube.

In witness whereof I have hereunto subscribed my name this 12th day of January,

WILLIAM BORKENSTEIN.
